This is my second MB. Very pleased w/first and mostly pleased with this one (E320, 2000, sedan). The problems are the automatic door locks (I have had them fixed several times only for them to disconnect or something again; second - the cassette player - fixed once, worked a short while - broke again. Other than that pleased - however, I drive it very infrequently.
Quality; sound system; space; conservative body style which does not drastically change from year to year.
Improve the automatic door locks and the cassette player.
